As a Roblox player, it is currently too hard to try out avatar thumbnail poses. To my knowledge, there is currently no native way to preview a pose on your avatar without buying it first and trying it. The closest you can get to previewing a pose is by playing a game like Catalog Avatar Creator where it plays the first keyframe of the animation, but this is not a guaranteed 1:1 match as the actual result will vary due to how the animation is rendered as well as the camera angle. This is not the game’s fault as it is just predicting what the emote will look like on your profile but it would be nice to have a “try on” button.
While I love this emote (Effortless Aura Pose), I expected it to look like I am floating but my foot does not fit in the image, the camera angle sucks and it looks like I am standing on one foot while facepalming not floating. There are definitely other emotes out there but my point is that I bought this emote expecting it to look the same as it does in-game.
If Roblox is able to address this issue, it would improve user experience because some users spend thousands of Robux trying avatar poses just to be disappointed by them due to lack of preview options with only my sense of judgement being through third party tools which also do not have a way to accurately display them since poses seem to show differently on the website than they do in-game.
